How much does eDiscovery cost?

The cost of eDiscovery depends on several factors, including data volume, review complexity, hosting requirements, technology, and the level of project management required. While no two matters cost exactly the same, legal teams can improve budget accuracy by understanding the biggest pricing drivers before collection begins.

In this guide, we’ll explain what influences eDiscovery cost, how to evaluate eDiscovery pricing, how to build an eDiscovery budget, and what questions legal teams should ask before approving a project. 

The cost of eDiscovery is driven by more than the amount of data involved. Collection strategy, review requirements, technology decisions, deadlines, and the complexity of the matter all influence the final cost. 

Understanding these factors early allows legal teams to create a more accurate budget, avoid unexpected expenses, and build a discovery strategy focused on the information that matters most. 

How much data needs to be collected?

Data volume is one of the biggest factors influencing the cost of eDiscovery. Modern legal matters often involve more than emails and PDFs. Today’s electronically stored information (ESI) can include collaboration tools like Slack and Microsoft Teams, cloud storage, mobile devices, shared drives, social media content, and other emerging data sources. 

When legal teams underestimate the volume or variety of data involved, costs can quickly increase. Broad collection efforts may result in unnecessary files being processed, hosted, and reviewed, increasing both technology and legal review expenses.

A targeted, defensible collection strategy can help reduce unnecessary data early in the process. By identifying key custodians, relevant data sources, and appropriate search parameters upfront, teams can focus resources on information that supports case strategy.  

How much document review is required?

For many matters, document review represents the largest portion of total eDiscovery spend. The number of documents requiring review, the complexity of the issues involved, privilege considerations, and review deadlines can all significantly impact costs. 

Inefficient review workflows can quickly increase expenses. Without proper technology, analytics, prioritization, and quality control processes, legal teams may spend significant time reviewing documents that ultimately have little impact on the matter.  

Working with an experienced Document Review Services provider can help legal teams create a review strategy that balances accuracy, efficiency, and defensibility. Modern review workflows may incorporate analytics, technology-assisted review (TAR), and AI-powered tools to prioritize relevant information and reduce unnecessary review effort.

Which technology and hosting model is used?

Technology choices can have a major impact on eDiscovery pricing. The right platform and workflow can help legal teams manage large volumes of information efficiently, while the wrong approach may create unnecessary costs and delays. 

Factors that may influence technology-related expenses include: 

• Cloud hosting requirements
• Active versus archived data
• Number of users accessing the platform
• Analytics and advanced search capabilities
• AI-powered review tools
• Data processing requirements
• Export and production needs

Selecting a platform that aligns with the needs of the matter can help legal teams control costs while maintaining a defensible discovery process. Learn more about Array’s approach to Platform Intelligence. 

What level of project management is needed?

Every matter requires a different level of support. Complex litigation involving multiple parties, tight deadlines, large productions, or specialized requirements may require more hands-on project management. 

Project management needs that can affect the cost of eDiscovery include: 

• Production schedules
• Rolling productions
• Privilege review and privilege logs
• Discovery deadlines
• Data source coordination
• Reporting and status updates
• Communication between legal and technical teams

An experienced project management team can help identify potential challenges early, keep workflows organized, and prevent costly surprises later in the matter. 

What factors have the biggest impact on eDiscovery pricing? 

Several variables influence the final cost of an eDiscovery project. Understanding these factors can help legal teams create more realistic budgets and compare provider proposals more effectively. 

How do eDiscovery providers charge?

• eDiscovery pricing varies depending on the provider, technology platform, scope of work, and requirements of the matter. Every provider structures pricing differently, which is why understanding what is included in a proposal is essential before approving a budget. 

• Common eDiscovery pricing models include: 

Per-gigabyte pricing

Some providers charge based on the amount of data processed or hosted. This model may be straightforward for matters where data volume is predictable but can become more complex as data volumes change. 

Subscription pricing

Some platforms use subscription-based models that provide access to technology and features over a defined period. 

Managed services pricing

Managed eDiscovery services may combine technology, project management, processing, review support, and other services into a broader engagement model. 

Flat-fee pricing

Some providers offer flat-fee pricing for specific services or phases of a matter. Legal teams should confirm exactly what is included before comparing proposals. 

Hybrid pricing models

Many matters use a combination of pricing structures depending on the technology, services, and level of support required.

Before selecting a provider, ask for a clear breakdown of included services, potential additional costs, and assumptions used to develop the estimate. 

How can legal teams estimate an eDiscovery budget?

Creating an accurate eDiscovery budget starts with understanding the scope of the matter and identifying the factors most likely to impact cost. 

Legal teams should consider: 

• Estimated data volume
• Number of custodians
• Anticipated review population
• Hosting duration
• Production requirements
• Matter complexity
• Discovery deadlines

While an estimate cannot account for every variable, early planning can help teams make informed decisions and avoid unexpected costs. 

What questions should you ask before approving eDiscovery costs?

Before approving an eDiscovery budget or selecting a provider, legal teams should understand exactly what is included and how costs may change throughout the matter. 

Important questions to ask include:

• What services are included in the quoted pricing?
• Are there processing minimums or additional fees?
• How are hosting charges calculated?
• What happens if data volume increases?
• Are analytics and AI capabilities included?
• Are project management services included?
• How are productions billed?
• Are exports, migrations, or additional support services extra?

Clear communication upfront can help prevent unexpected expenses and ensure everyone understands the scope, assumptions, and goals of the engagement. 

How can legal teams reduce the cost of eDiscovery?

• While every matter is different, proactive planning can help legal teams manage the cost of eDiscovery without sacrificing quality or defensibility.

Conduct early case assessment

The best opportunity to control costs is often before discovery begins. Early case assessment helps teams understand the available data, identify key issues, and develop a focused discovery strategy 

Cull data before review

Reducing unnecessary data before review begins can significantly impact costs. Deduplication, targeted searches, filtering, and analytics can help eliminate irrelevant information and focus review efforts on higher-value documents. 

Use AI and analytics strategically

AI-powered tools and advanced analytics can help legal teams prioritize relevant documents, identify patterns, and streamline review workflows. 

Work with an experienced provider

The right eDiscovery partner provides more than technology. Experienced providers help legal teams design efficient workflows, anticipate challenges, and maintain defensibility throughout the process.
